Should I take my friend's chicken into my flock?

My friend has a chicken who has spent the last year attacking two other chickens constantly, to the point of leaving those two bloody and isolated from the rest of her group. I have a flock of 10 week old chickens who seem to get along very peacefully so far.

The new chicken will need to be in quarentine for at least 30 days before being around your chickens. If it picks andpecks other chickens it will likely pick/peck/pluck and can kill your younger chickens.

I think you need to explain to your friend that she cannot dump her chicken into yours for first, biosecurity reasons. Do you want your chickens infected with anything hers might have? Second, if your flock is happy and peaceful, adding a strange chicken could make all of yours uneasy, aggressive, and uncomfortable. Chickens do best when they are happy with their flock mates and no strange birds are added. If she is not happy with her bird, she needs to dispose of it herself. You can take it, but only if you WANT it, and I would be sure and quarantine it for 30 days before trying to introduce it to your flock. If it is used to picking on other chickens, it will continue to do so.

Accept mean chicken. Then cull it when your friend leaves. You can always say 'hey, it attacked my babies'. I have a tough time saying no too, but I wouldn't want my own birds to even take the risk of getting hurt.

Take if from me, someone who has experienced it. It can be devastating and such a heartache. Stand up for your chicks and say, "NO!" MissPrissy speaks wisely when counseling you to do the same. I just had to cull 9 of my 5 wk. olds today. It was not fun and something I don't wish you to go through. You are in charge and you need to say no. You don't need that mean chicken in your flock anyways. It sounds like the best place for it would be the dinner table.
